Welding performed under water can be of two types: dry welding and wet welding. In dry welding, a hyperbaric chamber filled with gas is used so that water cannot access the welding site. In wet welding, gaseous bubbles are expelled around an electric arc as the process is done to shield the weld while also providing safety to the diver by moistening the area preventing conduction of electricity through water. The water bubbles may interfere with the weld area which make the welding practice processes more complex necessitating extra precaution.
